Abstract (en)
A porthole gasket (57) and an assembly and a heat exchanger (31) are provided. The porthole gasket is arranged for installation between a corrugated first plate (41) and a second plate (33) of a heat exchanger (31) such that a central extension plane (e-e) of the porthole gasket is parallel to the first and second plates. The porthole gasket is annular and arranged to enclose, within an inner periphery (58) of the porthole gasket, a porthole area (43) of the first plate and a porthole area (34) of the second plate. A first surface (60) of the porthole gasket, which is arranged to engage with the first plate, is corrugated so as to define alternately arranged gasket ridges (62) and gasket valleys (63) along a longitudinal extension (L) of the porthole gasket. The gasket ridges and gasket valleys are arranged to mate with plate valleys (49) and plate ridges (47), respectively, of the first plate. A second surface (61) of the porthole gasket, which is arranged to engage with a plate arrangement comprising the second plate, is essentially plane and arranged to contact an essentially plane surface (38) of the plate arrangement. The gasket ridges protrude, and the gasket valleys descend, in a normal direction (n) of the central extension plane. Widths (w1-w7) of the porthole gasket are measured parallel to the central extension plane and perpendicular to the longitudinal extension of the porthole gasket.
